whats up guys, just bought a db2 integra. 92 gs-r with the b17 for all of you that dont know, lol. car runs great, idles smooth, and starts up everytime. once it warms up, it idles around 600 or 700 which im guessing is normal. only thing im noticing is that it will bog sometimes if im around 2500 rmp or lower. it doesnt happen all the time, only sometimes. for instance, if im going up a hill and at about 4k in 3rd and shift into 4th, the rmp's will drop to about 2500 and it will bog until i shift down. anyone know what might cause that? im gonna do an oil change and change plugs and wires this weekend but what else could it be? motor was recently rebuilt so i don't think its that. could it be coil or something else? thanks in advance for any help!
